i just picked up the two used with no directions and i hooked up the ebc and it works fine, the power meter i got to turn on and all but the one wire that u are supposed to tap into the ecu i have not done yet because i don't know which wire i am supposed to use, i know it is a green and white but there are a few, also the wiring of the power meter to ecu should be same for 02 to 04 wrx's right,

thanks
Dan
